Looking at the schematics of the sturmey archer S2C hub I noticed this part:

2     HMN425    Brake Adjuster Nut (Xylan) 

And I was wondering, what does it exactly adjust? Does it adjust the brake power? Or just the position of the brake arm? Or something else brake related?

    You screw it in until the brakes are tight, then back it off a little. – Daniel R Hicks Feb 21 '20 at 13:37
  • So you are saying it's not adjusting, it's more like securing/holding the brake parts? How do you know the brakes are tight? Or do you mean 'until te nut is tight' ? – Sebastian Feb 21 '20 at 13:59

    If the nut's too tight the brakes wheel won't turn. You want it loose enough that the brakes don''t drag, but tight enough that the brakes work when activated. I learned this when I was about 12. – Daniel R Hicks Feb 21 '20 at 14:19
  • @DanielRHicks is it a bit like the adjuster barrel on road dual pivot brakes, then? – Weiwen Ng Feb 21 '20 at 14:39
  • @WeiwenNg - A little bit. But the hub brake adjustment is far less fussy. – Daniel R Hicks Feb 21 '20 at 17:14
